Shredding security level

Article Number: 5307 | Last Updated: Tue, Oct 2, 2012 3:53 PM

When you delete a file from your hard drive, your operation system only removes the pointer to the file without actually overwriting the data on the disk. UltraSentry eliminates the pointer to the file and overwrites the file's data using U.S. DoD (Department of Defense) standards for data destruction, providing a secure and unrecoverable delete. The File Shredder provides three security levels by default. This command assigns a security level to the shedder. The shredder will operate according to the security level that is selected. The drop down menu will display the available levels.

Default Security Levels:

1) DoD Level C = 1 pass, secure, fastest

This deletion method deletes the file pointer from the file table and overwrites the original file data with a single character (0x0).

2) DoD Level D = 1 pass, more secure, faster

This deletion method deletes the file pointer from the file table and overwrites the original file data with 3 characters (0x0, 0xFF, and one other random character).

3) Shell Level = 2 passes, most secure, fast

This deletion method deletes the file pointer from the file table and overwrites the original file data with 3 characters (0x0, 0xFF, and one other random character), then does it again on the second pass.

Custom security levels can be created in the Security section of Preferences. A user can define which characters to use for overwriting and specify the number of passes.
